With the foregoing and other objects which may hereinafter appear, thisinvention consists of the novel construction, combination andarrangement of parts as will be more specifically described and as areillustrated in the accompanying drawings wherein is shown embodiments ofthe invention, but it is to be understood that changes, variations andmodifications may be resorted to which fall within the scope of theinvention as claimed.

In the drawings:

Figures 1, 2, and 3 are respectively an end view, a cross sectional viewand a front elevation of the tool,

Figure 4 is a perspective view of the form of end retainer employed forthe cleaning elements,

Figure 51s a cross sectional view of a modified form.

Figure 6 is a cross sectional view of still another modified form,

Figure 7 is a side elevation, broken away, of the form shown in Figure6, and

Figures 8 and 9 are perspective views of the cleaning elements of theform shown in Figure 6.

The tool, with reference to Figures 1 to 5. includes an elongatedcarrier or holder 8, a handle I, a pair of oppositely disposed endretainers I. 9 of like form and a pair of oppositely inclined cleaningelements extended from the forward or leading corners of the carrier 8.

In Figures 1, 2, and 3 the cleaning elements are designated IO, N and inFigure 5 are indicated at l2, It. The difference between the form shownin Figures 1, 2, and 3 with respect to that shown in Figure 5 residessolely in the construction of one of the cleaning elements. Otherwisethan that as stated the form shown in Figure 5 will be the same as thatillustrated by Figures l, 2, and 3.

The carrier or holder i is in the form of an elongated substantiallysolid block it ofsubstantially rectangular parallelepiped contour. Theblock may be formed of any suitable material and preferably wood will beemployed. The block it includes a rear flat upstanding rectangular fol-35 lower face or side Ii, a horizontally disposed lower flat rectangularfollower face or side it, a horizontally disposed upper flat rectangularfollower face or side I1 and an upstanding flat rectangular leading faceor side it. The ends of the block are of substantially square contour.when the tool is used, the block is disposed in a manner whereby thefaces II and II will extend at a forward inclination from bottom to topand the faces 18, ll forwardly at a downward inclination from the faceIt. The leading-face it is of less length than that of the faces l5, l6,and H. The side faces I6, I! are of different lengths and of less lengththan that of the faces I! and II. The faces It, I! merge at theirfollower ends into the ends of face IS. The leading ends I9, 20 of facesl8, l1 respectively are spaced outwardly adjacent to the ends 2|, 22 ofthe face I I. The ends II, 22 are arranged inwardly with respect to theends of face It. The width of faces l5, l8, l1, and I8 correspond. Theblock I4 is formed centrally with a threaded socket 23 opening at therear face I! for the reception of the threaded end terminal portion 24of the handle ,7 whereby the latter and carrier i are secured together.The socket I3 is intersected by the transverse and longitudinal mediansof the block ll.

The block I4 is formed with a pair of oppositely disposed diagonallyextending grooves 25,

- choring the ear '43 to carrier 6.

26 opening at their ends at the leading corners of block M. The grooveis of greater depth and width than groove 26. The side walls 21, 28 ofgroove 25 merge into the leading end l9 of face |6 and into the lowerend 2| of the face l8 respectively. The side walls 29, of groove 26merge into the leading end 20 of face l1 and into the upper end 22 ofthe face"|8 respectively.

With reference to Figures 1, 2, and 3, the carrier 6 is. shown as havingextending into the grooves'25, 26 thereof cleaning elements IO, Mrespectively. The element I6 is of the brush type and includes a head 3|corresponding in length to that of groove 25. The head 3| is providedpreferably with a pair of spaced parallel channels 32, 33 opening at thesides thereof. Anchored in and extending from the grooves 32, 33 are therows 34, 35 respectively of tufts of bristles arranged in a manner toform a flared brush- ,ing means. The head 3| is secured, by any suitablecementitiousmaterial, in groove 25, completely fills the latter,"isflush with the end |9 of face I6 and extendsbeyond the end 2| of face I8. The element II is of the squeegee type am is formed of a series offlared laminations 36 of rubber. The element H is secured, by anysuitable cementitious material, in and completely fills the groove 26,as well as extends outwardly from thelatter. The elements IO, N are disposed at opposite inclinations with respect to each other and diagonallyrelative to carrier 6.

The retainers 8, 9 are. of like construction and each is connected to anend and the leading face of the carrier. The retainers 8, 9 act toprotect the ends of and prevent the cleaning elements, which are mountedin and extended from the carrier or holder 6. from shifting lengthwiseof the latter. Each retainer includes a plate 31 having oppositelycurved inclined forward or leading corners 38, 39 and a forward orleading end 40 of less length than its rear or follower end 4|. Thecorner 38 is of greater length than corner 39 and has its ends aligningwith the end |9 of face l6 and the end 2| of face |9 of carrier 6. Theends of corner 39 align with the end 20 of face H and the end 22 of facel8 of carrier 6. The sides 42 of plate 31 are flush with the faces Hiand ll of carrier 6. The end 4| of plate 31 is flush with the face |5 ofcarrier 6. The plate 31, at its forward or leading end, is formed with atapered inwardly extending aperturedear 43 positioned against the face|8 of carrier 6. The aperture in ear 43 is indicated at 44 and throughwhich extends a holdfast means 45 for detachably an- The ear 43 isdisposed at right angles to the forward or leading end of plate 31. Thelatter, in proximity to its rear or follower corners 46, is formed withopenings 41 for the passage of holdfast means 48 fordetachably anchoringthe plate 31 to an end of the carrier 6.

With reference to the modified form in Figure 5 the cleaning element I2is of the same form as element In. The cleaning element I3 is a polisherand of the squeegee type. The element |3 consists of a strip of felt 48which is to be of the same contour as that of element The element l3includes a contracted inner portion 49 completely filling groove 26 anda non-contracted outer portion '50. Otherwise than that as stated theform of tool shown in Figure 5 would be the same as that shown inFigures 1 to 4.

The inclined corners 38, 39 of the plates 31 prevent the extendingofl'the plates to overlap the bristles at the ends of the rows outwardlyadjacent to head 3|, as well as preventing the extending of the plates31 to overlap the ends of elements l3 outwardly adjacent the carrier 8whereby lateral end movement of the brushes and elements |3 will not beretarded when the tool is active.

With reference to Figures 6 to 9, the tool 48 includes a carrier orholder 49 and a handle 59. The carrier 49 is of the same form as thecarrier 6, with the exception that it is formed with two pairs of spacedthreaded openings extending inwardly from its leading face 5| to thegrooves 52, 53 which receive the cleaning elements. The openings of onepair are designated 54 and communicate with the groove 52. The openingsof the other pair are indicated at 55 and communicate with groove 53.The openings 54 align with the openings 55. The grooves 52, 53 are oflike width and depth and are arranged in the carrier 49 in the samemanner as the grooves I9, 20 are arranged in the carrier 6. Otherwisethan that as stated the carrier 49 and handle will correspond to that ofcarrier 6 and handle 1. In the tool shown in Figures 6 to 9 retainers56, 51, corresponding in form and arrangement to the retainers 6, 9, areemployed.

The tool 48 includes a cleaning element 58 of the brush type formed of ahead 59, a body of bristles 66 and a resilient apron 6| encompassing thebody of bristles. The apron 6|, at its inner end 62, is anchored to theouter face of head 59 and has its outer edge 63 positioned in proximityto the outer end 64 of the bristles 60. The apron 6| is preferablyformed from a. sheet of rubber. The head 59, at one side, is formed witha pair of spaced aligning cavities 65. The head 59 is arranged in thegroove 52 in the same manner as the head 3| is arranged in groove i9.When head 59 is positioned in groove 52, the cavities 65 align with theopenings 54. The element 58 is detachably secured in groove 52 by a pairof binding screws 66 which extend through the openings 54 and bindagainst the walls of the cavities 65. The apron 6| acts to prevent thescattering of the dust or dirt and further acts to keep dust or dirt,threads and other particles from getting caught in the bristles.

The tool 48 also includes a cleaning element 61 functioning as apolisher and is of the squeegee type and includes a head 68 and a stripof felt 69 formed of a contracted inner portion 16 and a non-contractedouter portion 1|. The portion 1| is arranged within and secured to head68. The latter has one side formed with a pair of spaced aligningcavities 12. The head; 68 is positioned in groove 53, and when sopositioned j the cavities 12 align with the openings 55. The

element 61 is detachably secured in groove 53 by a pair of bindingscrews 13 extending through openings and bind against the walls ofcavities 12.

The heads 59, 681 of elements 58, 61 respectively are of the same sizewhereby provision is had for the interchanging or selective positioningof the elements 58, 61 relative to the grooves 52, 53.

The bristles may be anchored to head 59 in any suitable manner, butpreferably head 59 will be formed with a pair of parallel channels 14.The tufts of bristles are anchored in the channels whereby they arearranged in parallel rows. The head 68 is formed with a groove 15 toreceive and contract a part of the strip of felt 69.
